D113 is a premium grade, weak acid, macroporous, cation resin supplied in the hydrogen form as moist, tough, uniform, spherical beads. Its ion exchange functionality is derived from the carboxylic group, which is easily converted to the hydrogen form and has a high affinity for divalent ions.D113 is intended for use in hydrogen cycle dealkalization, deionization, and chemical processing applications. D113 can also be supplied in the sodium form for use in sodium cycle applications such as softening and removal of heavy metal cations. 2.Typical Physical and Chemical Properties: Items Specification Polymer Matrix Structure Acrylic Crosslinked with DVB Physical Form and Appearance Macroporous spherical beads Functional Groups R-COOH Ionic Form ,as shipped H+ Total Capacity, H+ form, wet, volumetric 4.2 eq/l min Moisture Retention, H+ form 45-52% Particle Size Range 0.3mm-1.2mm
